Cologne Cathedral: A 632-Year Journey to Gothic Splendor #history

The Cologne Cathedral, which is also believed to be interfered by the devil among the people because it was not finished for centuries, could only be completed after 632 years. Cologne Cathedral, which faced many difficulties over the years during its construction, is one of the rare buildings that survived World War II. The main reason for the black color of the cathedral was the acid rain after World War II.
